[Joint Effort and Attacks that target multiple characters]

Would this apply to rapid fire effects or other attacks that generate follow-up attacks?

[Gotta Get Some Air interaction with Cat and Mouse]

Had a question pop up, if an X-force player were to use Cat And Mouse after deployment/pre round 1 and have the character placed within 2 of Logan, The Wolverine would Logan both be able to play Gotta Get Some Air and also not suffer the effect of being unable to contest objectives round 1 as its happening prior to the round starting? My reading of it was yes but I just wanted to confirm for our play group.

[Dormammu's Dark Miasma vs Ronan's The Accuser]

Had a situation come up in game where Dormammu's Incantation of Obliteration KO'd Ronan while having the results to trigger Dark Miasma. If Ronan activates The Accuser does Dark Miasma still resolve first off of Ronan's current position  (and any subsequent potential Dark Miasma attacks) or does Ronan resolve The Accuser before Dormammu resolves the next attack?
